Abstract (en)
A packet switching system has at least first and second packet level control devices (101, 102) and first and second frame level control devices (201, 202). When a data packet (DT) is received at the first frame level control device via a communication line which is connected thereto, the first frame level control device disassembles the data packet and transfers only a header portion (PH) of the data packet to the first packet level control device, thereby a data portion (UD) of the data packet being transferred directly to the second frame level control device. The second frame level control device assembles the data portion received from the first frame level control device and the corresponding header portion received via the first and second packet level control devices, and transmits the assembled data packet on a communication line which is connected to the second frame level control device.
